So long as the reason why someone is paid more is also public then it's fine. You're assuming perfectly rational behavior, which is... not human. I'm not arguing against open salaries (I am in such condition), but assuming rational actors is not realistic. In particular, an example justification along the lines of "X takes more because is a better programmer than you are" is very dangerous, not only in the obvious way.
